Why can't ...mapGetters be unpacked into data?

Question

Vue.js

Why do you need to unpack in computed , and not like this, for example:

export default {
    data(){
        return{
             ...mapGetters([
                'doneTodosCount',
                 'anotherGetter'
                  // ...
            ])
        }
    }
};

Answer 1

From the vuex docks , the mapGetters
function simply proxies the store getters into the component's local computed properties.
That is, it turns intomapGetters(['doneTodosCount'])

{
  doneTodosCount() {
    return this.$store.getters.doneTodosCount;
  },
}
